Ti Gas Tungsten Arc Welding: Problems and Remedies
Welding Ti alloys with the gas tungsten arc process presents distinct problems beyond those encountered with steel. The metal's high reactivity, resulting oxide formation that can cause inclusions and brittle ductility, is a major concern. Furthermore, titanium's low thermal response makes controlling the HAZ challenging. Approaches involve meticulous preparation to remove oxides before and during joining, employing protective atmospheres like argon or He to inhibit reaction, and utilizing controlled welding parameters – including lower power and suitable travel speeds. Proper method and skill are essential for successful Ti alloy joining.
